IMPROVED Bares-Kan.-

TO ALL WHOM IT -MAY CONCERN:

Be it known that I, WILLIAM A; SHEPARD, of the city of New York, in thecounty of New York, and State of New York, have invented a new anduseful improvement in Kilns for .Heating and Hardening Bricks, Tiles, orother substances; and I do hereby-declare that the following is a full,clear, and exact description thercof,'rofcrence being bad to'thcaccompanying drawings, and to the letters of reference marked thereon.Inv

the accompanying drawings- Figure 1 is a side elevation of a kilnconstructed according to my invention; and

FigurcQ is alike view with the side wall removed to show the interiorstructure of the kiln.

I build an oblong room of brick, or other suitable material, of anyconvenient size, say eight feet wide, forty feet long, and ten feethigh, and lay a railway track through the same, terminating at each endconveniently for loading and unloading the cars hereinafter described. Idivide the long room into as many compartments as may be desirable byvmeans of movable sheet-metal partitions, which slide up and down, butwhich co1npartments communicatealternately through open spaces at thetop and bottom of said partitions, and thus a current of hot'ai'r passesunder one partition and over another. through the entire length of theroom. I constructa car for each compartment, which ear'ha's a fire-brickplatform upon which I build a brick-kiln, or place other materials forburning or drying. g

In the accompanying drawings A A is-the outer brick wall of the longroom, above described, anda adoors to close the openings in said wall,through which fuel is introduced into the arches of the kilns. C C arethe cars, upon the fire-brick platforms 0 of which the brick-kilns B arebuilt. 'Thcse cars main and out upon railway tracks t. pp are thesliding partitions between the different compartments, with spacesalternately under and over them for the hot air to pass through, asabove described. R is a roof covering the long roomand enclosing it,with openings for the partition-plates to slide up and down in.

The fire-brick platforms of. the cars are on' a level with the lowerpart of the openings in the outer wall through which the fuel isintroduced. The cars, having each a brick-kiln built thereon, are drawninto the loiig.

room, one in each compartment, and the several partitions lowered down.Thecnd doors of the long room are then closed, and all the side doors11, except the one most distant from. the chimney, through which openinga fire is built in the first compartment or kiln. When the fire beginsto burn a draughtwill be created, which will convey the flame and hotair through-all the compartments and out at the chimney, passingalternately under one partition and over another, as above described,drying and seasoning the bricks in the kilns, which as yet have had nofire under them. When the first kiln is nearly burned or hardened, Iplace fire in the second kiln and increase it at pleasure, and when thefirst kiln is finished the car supporting it is drawn out and its placetaken by the second kiln, and the last compartment is supplied with afresh kiln.

When brick are made of wet clay the room should beimade longer, or asecond story should be constructed for the purpose of drying the-brickon the principle of a return-flue, with the'ehimney at the front end ofthe room. 1

What I claim as my invention, and desire to secure by Letters Patent,is-- p 1. An oblong building with a railroad track running through itswhole length, and divided into separate compartments by means ofremovable partitions, in combination with a series of cars havingfire-brick, or other equivalent platforms, and adapted to building kilnsthereon, and burning the same on the cars,-substantially as;

described.

2. I also claim building and burning kilns of brick, pottery, or othersimilar substances, on movable railroad cars, with platforms offire-brick, or equivalent material, substantially as described.
